A prominent class of motor neurons in the sympathetic nervous system are involved with vasoconstriction also with an increase in the heart rate.

How does the sympathetic nervous system work in stress?
The sympathetic nervous system is the part of the autonomic nervous system originating in the thoracic and lumbar regions of the spinal cord that in general inhibits or opposes the physiological effects of the parasympathetic nervous system, as in tending to reduce digestive secretions, speeding up the heart, and contracting blood vessels.
What known functions result from sympathetic innervation into kidneys?
regulation of blood flow
What is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
Can central nervous system damage lead to malfunction in the lymphatic system?
For clarity, let us consider the systems before we address this question.The lymphatic system filters the fluids that bathe cells in the body, trapping bacteria and viruses in lymph nodes. From here immune responses can be mounted to clear the invading matter. A part of the nervous system, referred to as the sympathetic nervous system, does indeed connect with these lymph nodes. This particular arm of the nervous system normally prepares the body to better cope in situations of stress (fight, flight, fright response). So this implies that the immune system may be shunted into a higher level of function in times of acute stress. It also might explain why chronic stress has the opposite effect via desensitization, meaning a greater change of infection.Now, since the connection is via the peripheral nervous system, and the role is modulatory, it follows that CNS damage - assuming it is non-fatal and does not result in profound loss of function - would not lead to 'malfunction' in the lymphatic system. But it could lead to acute of chronic changes in immune responsiveness, depending on sympathetic activation.
Diseases of the nervous system may result from?
Nervous system diseases can result from a number of factors. Not all diseases are fully understood yet. Causes may be genetic or environmental / toxins. Though injuries account for many nervous system disorders and conditions, these problems are not diseases.
The fight or flight response is a direct result of the activation of the...?
...sympathetic nervous system. When faced with a threat, this system triggers a series of physiological changes to prepare the body to either confront the danger or flee from it. Key components of the fight or flight response include increased heart rate, heightened senses, and the release of stress hormones like adrenaline.
Pupil dilation and rapid heartbeat are the result of activation of which branch of the autonomic nervous system?
peripheral nervous system
How does the parasympathetic nervous system affect constipation?
The parasympathetic nervous system allows for the relaxation of the GI muscles, which allows excretion. So in other words, constipation is more a product of the sympathetic nervous system, which if stimulated, will divert blood flow from the gut and delay defecation, causing constipation. If the parasympathetic nervous system is blocked or the sympathetic system stimulated, constipation can result.
How might inhibiting the sympathetic nervous system act to lower blood pressure?
It will help to calm you down and make you feel less nervous or anxious. This will result in a lowering of blood pressure.

What part of the nervous system is responsible for heart rate breathing and trembling?
Heart rate and breathing are regulated by a part of the brain stem called the medulla oblongata. This part of the brain stem controls breathing,heartbeat and articulate speech. As far as trembling that is a result of the automatic nervous system activation. It can also increase heart rate and increase breathing rate but it is not a control for these three. This part is called the sympathetic half of the autonomic system, the other half is the parasympathetic. You can not live without the medulla. A blow to that area will kill.
What would result if the sympathetic system was damaged?
There is no sympathetic system in your body. The closest thing to emotions or feelings is arguably either the heart, brain, or soul.
What known functions result from sympathetic innervation into kidneys?
regulation of blood flow
Why does crystal meth make a person so horny?
Methamphetamine mimics the effects of the sympathetic nervous system. The sympathetic nervous system is subdivision of the Autonomic or "Automatic" nervous system. Whenever you hear "Fight or Flight", they are talking about Sympathetic. When activated, the Sympathetic Neurons cause a release of specific chemicals responsible for movement, alertness, and sustainence. These chemicals are epinephrine(adrenaline) from the adrenal medulla and norepinephrine (noradrenaline). More importantly, dopamine (The Pleasure chemical) is released at 6x it's normal amount with meth use, and causes that rush and euphoria. Your pupils dilate giving you a wider field of vision, your heart rate increases, and your heart's contraction force increases as well, allowing you the energy you need to "Fight or Flee". The emotional seat of the brain is known as the "Limbic System". This system is a series of structures and pathways through which dopamine and other neurons travel. If dopamine hits the nigrostriatal pathway; the effect is usually paranoia, while if it his the mesolimbic pathway, the effect is intense euphoria. Your sex drive is a result of the limbic system. Therefore, if stimulated just right; sex drive will increase.

Are sweat glands parasympathetic or sympathetic?
They are sympathetic but an exception - ACh is released as a post-synaptic neurotransmitter rather than Adrenaline/Noradrenaline.Illicitinga parasympathetic response will not stimulate these neurons and therefore sweating is not a parasympathetic side effect.However, as post-synaptic sweat glands contain Muscarinic receptors and not adrenoceptors the administration of a non-selective Muscarinic agonist would result in both a parasympathetic response such as constriction of the pupil or decreased heart rate as well as sweating due to the activation of these sympathetic post-synaptic MAChR in the sweat glands.Atropine would reduce all parasympathetic responses and stop sweating.
